Application February 16, 1934, Serial No. 711,544 3 Claims. (Cl. 229-86)This invention relates to new and useful improvements in envelopes.

The invention has for an object the construction of an envelope which ischaracterized by the arrangement of a wire within one side thereofattached at the ends upon opposite corners, of said side and detachablyarranged to facilitate the opening of the envelope.

More particularly the invention also contemplates the provision ofreinforcement pieces secured upon said detachable corners to facilitatethe removal of the corners for the opening of the envelope.

Still further the invention proposes the provision of perforations asthe means for rendering said corners readily detachable.

Another one of the objects of this invention is the provision of sheetcorner pieces secured within the detachable corners of the envelope and2G having bayonet openings coactable with enlargements upon the ends ofthe wire arranged Within the side, for attaching the wire upon thecorner pieces to facilitate .the opening of the envelope.

Still further the invention proposes the construction of an article asmentioned which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of an envelope with a wire opener onone side.

Fig. 2 is a perspective enlarged view of one of the reinforcements usedin Fig. 1.

Fig. 3 is a fragmentary view of a corner of the envelope illustrated inFig. 1 but shown with the reinforcement removed. f

Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 3.

Fig. 5 is a view similar to Fig. 3 but illustrating the invention.

Fig. 6 is a detailed view showing in side elevation the sheet cornerpieces and the wire therebetween for use in the envelope illustrated inFig. 5.

Fig. 7 is a sectional view taken on the line 7-7 of Fig. 6.

The envelope with the wire opener on one side comprises sheet materialin the form of an en.- velope 10 and having opposite corners 11 on oneof the sides, such as side 12, formed by lines of perforations 13 sothat the corners 1l are readily detachable. A wire 14 is arranged withinthe side 12 and is attached at the ends upon the detachable corners 11.More particularly each of the ends of the wire engage several timesthrough and around the detachable corner pieces 11 producing the turns14 clearly illustrated in Figs. 3 and 4. These turns serve to accomplishthe attachment of the ends of the wire upon the corner pieces.Reinforcement pieces 15 are secured by glue, cement or the like upon thedetachable corner pieces 11 and serve to cover and attach the turns 14'upon the corner pieces, and furthermore serve to reinforce the cornerpieces so that 'they may be easily gripped to be detached.

The envelope may readily be opened by tearing one or the other of thecorner pieces 1l or gripping the reinforcement pieces 15, and pullingand drawing upon the wire 14 to cause the wire to cut 75 the edge 12open.

In Figs. 5, 6 and 7 the invention has been disclosed which distinguishesfrom the prior form merely in the manner in which the ends of the wiresare attached upon the corner pieces. More 80 particularly, in the latterform illustrated, the envelope 10 is provided with detachable cornerpieces 11 produced by the perforated lines 13. These corner pieces llare on opposite ends of the side 12. Sheet corner pieces 16 are 85secured within the detachable corners 11 and have bayonet openings 17 atinclinations with the smaller ends at the bottom diverging to the topand for coaction with the ends of the wire 14 extended along within theside 12. More particularly the wire 14 has its ends formed withenlargements 18 comprising portions thereof formed into knots. Theseenlarged ends 18 are of'such size so that they may pass through thelarge portions oi' the bayonet slots 17. 95 and when the ends are moved,into the smaller portions of the bayonet slots. Then the wire is firmlyattached upon the corner pieces. Each of the corner pieces 16 isprovided with a section 19 adapted to be pasted or in any other mannersecured Within the detachable corner 11. As illustrated the pieces 19are gummed to facilitate the attachment. Each of the detachable cornerpieces 11 is reinforced with the reinforcements 15 so as to provideadditional means by 105 which they may be readily gripped and detached.

YThe feature of the bayonet slots 17 and the corner pieces 16 is thatadjustment is readily possible to set the corner pieces 16 at distancesfrom each other when the wire 14 is stretched 110 straight, so that thecorner pieces may rea ily fit within the corners of one side of theenvelope. It will be understood that when the wire 14 is formed withknots it will not be of exact predetermined length, but a selection ofbayonet slots 17 would adjust for said variation. Still further the endsof the wire may be produced with diiferent types of enlargements, and insuch event, the adjustment permitted by selections of bayonet slotswould be useful in adapting the arrangement to envelopes of slightlydifferent sizes.

The opening ci the modified form of envelope is identical to the formpreviously described. One or the other of the corners may be detachedand then the Wire 14 drawn for causing cutting of the side 12 to openthe side.

While I have shown and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modications coming within the scope of the invention asdefined in the appended claims.

' Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:-

1. An envelope, comprising sheet material in the form of an envelope andhaving opposite corners on one side formed by lines of perforations sothat the corners are readily detachable, sheet corner pieces securedWithin said detachable corners and having bayonet openings, and

a. wire within said side of the envelope and having enlargements at theends engageable with said bayonet openings for attaching the wire uponthe corner pieces.

2. An envelope, comprising sheet material in the form of an envelope andhaving opposite corners on one side formed by lines of perforations sothat the corners are readily detachable, sheet cerner pieces securedwithin said detachable corners and having bayonet openings, and a wireWithin said side of the envelope and having enlargements at the endsengageable with said bayonet openings for attaching the wire upon thecorner pieces, said corner pieces having portions pasted within saiddetachable corners to comprise the attachment of the corner pieceswithin the detachable comers.

3.. An envelope, comprising sheet material in the form of an envelopeand having opposite corners on one side formed by lines of perforationssothat the corners are readily detachable, sheet corner pieces securedwithin said detachable corners and having bayonet openings, and

a wire within said side of the envelope and having enlargements at theends engageable with said bayonet openings for attaching the wire uponthe corner pieces, said bayonet slots having their reduced portionssloping towards each other so that the distance therebetween is smallerthan the distance between the large portions to prevent dispiacement ofthe wire once engaged.
